SpeedRicer's Intake System

Whenever you are designing an engine, it is important to set the objectives to achieve. In our case, SpeedRicer's 4g93t would only be race in quartermile-sprint events. We plan to rev our engine up to 9000-10000rpm range. It is important to choose the right intake manifold that would support our targeted Rpm range.
Quite a few options exists in the market for 4g93t gsr engine but most of them are immitations (skunk2, jun style,etc..) leaves us with 2 options namely Edelbrock's VictorX & Velocity's custom drag manif.

  

As we are decided not to fiddle with gearing ratios and such.. it is crucial for us to be able to rev higher in return shift gear later.
